Abstract

In order to improve the stability of the beam pattern, a newly adaptive beamforming method (SPAPES, Space-Polarization Amplitude and Phase EStimation) for vector sensor array is presented in this paper. The signal model is introduced first, and the principle of the proposed method has been discussed, and then the optimal weight vector is derived. The desired signal will be cancelled out when calculating the covariance matrix, thus the optimal weight vector is irrelevant to the desired signal. Simulation results indicate that SPAPES can achieve a good filtering performance under the circumstances of high desired signal power, low sampling snapshots and coherent interference signal.
